Several problems of automatic dispensing machine is generally a drain plug, glue, wire drawing, dispensing valve wear, these are the problems that need attention, are the main problems affect the dispensing operation, how the problems need to be solved, or dispensing task cannot be resolved, in the limited arrangement a set of these approaches to the problem. Jam is a common problem, with different drawing condition, the general jam is automatic dispensing glue is not clean, resulting in second times there will be congestion problem, the solution is very different, the use of cleaning liquid which is the most simple way. It is also important to prevent the precision of the glue dispenser from being destroyed. Although the dispensing valve wear, although the glue of automatic precision dispensing machine, but there is also a friction coefficient. For a long time, the dispensing machine will also be damaged, making a period of time for automatic dispensing machine maintenance, otherwise it will be maintained every day, as long as the maintenance work can be done.
